SPRING-MOTOR.

SPECIFICATION forming part of Letters Patent No. 413,356, dated october22, 1889. i Application filed October 15, 2,888. Serial No. 288,175. (Nomodel.)

To all whom t may concern:

Be it known that I, HENRY WESTPHAL, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Spring-llIotors, ofwhichthe following is aspeciiication, to wit:

This invention relates .to improvements in spring-motors for showinggoods; and it consists in certain peculiarities of the construction andarrangement of the parts, as will be hereinafter more fullyset forth anddescribed, and pointed out in the claims.,

To enable others skilled in the art to which my invention pertains tomake and use the same, I will now proceed to describe it, referring tothe accompanying drawings, in whichi Figure lis a" central verticalsection of my invention. Figjla is a detail view of bearing F. Fig. 1bis a detail view Yof l the shaft G, showing the anti-friction rollers orballs.V Fig. 2 is a detail horizontal section on line 2 2 of Fig. l,showing anti-friction rollers and powerspring. The gear-wheels andpinions shown in this figure are not shown inFig. 1, but are a portionof an ordinary train of gearing. Fig. 3 is a detail elevation ofpin-wheel D, pinwheel trip d, and a portion of large spring-` Wheel B,on which the pin-wheel trip is pivoted. Fig. 3 is a det-ail view takenon a horizontal line through disk or pin-wheel D. Fig. 4 is a detailelevation` of spring-wheel A and ratchet a, showing it in contact withspringpawl g on collar g, which is rigid with shaft G'. fFig. 5 is a'detail view of the drive-gear O and its ratchet and pawl, and Fig. 6 isa detail plan view of the release-stop c for spring-wheel A. v

Similar letters refer to like partsin the several views.

A is a frame-work consisting of a bottom and side plates and uprightstandards between, and connected therewith are the several parts of mydevice, as will be presently explained. l

A2 is the bottom plate.

A8 and A4 are the standards or supports, and F the top plate.

G is a shaft, which is journaled on the bottom plate A2 and extendsvertically up through the intermediate plate B and the I Wheel C. l

Above the plate B', upon the shaft G, I provide two or more cog-wheelshaving connected therewith a motor-spring, a wheel, and trip mechanism.I will now describe one of the same in detail.

g is a collar rigidly secured to the shaft G, revolving therewith,having thereon a springpawl g', which contacts with a ratchet a, onspring-wheel A. `The wheel A is provided with a collar O6. The saidcollar on its bearings with the shaft is provided with the antifrictionrollers co2 a2. `Upon the wheel A, I place a motor-spring A5, which atone end is connected to the side frame A4 and at the other to the hub ofthe wheel A. Upon springwheel A, near its outer edge, I place a trip cl,which contacts with the pin-wheel mechanism, as presently explained.Below this springwheel A, I mount ina similar manner a like spring-wheelB, which has the same kind of collar, spring, ratchet, and pawl asdescribed in reference to the wheel A. Extending vertically from theintermediate plate B to the top plate F is a standard A6. `Upon this d2,and one di longer than the others, the pins corresponding to the numberof the revol`u tions of the spring-wheel, the pin da being. struck afterthe spring-wheel has spent its force, thereby releasing the otherspringwheel and allowing it to work, so as to continu e the revolutionof the shaft G, the springwheel not in revolution ,having been held atrest by means of the dog E, having lock e, which is hung on the uprighta, the lock e engaging in teeth on the spring-wheel.

To prevent any irregular motion of the pinwheel D, I provide a lightspring I, which has one end loose contacting or which engages ICG withthe wheel D, and having its other end rigidly secured to the standarda6, as shown in Fig. 3 of the drawings.

As will be seen from the drawings, I have shown two spring-wheels-B thelower and A the upper-but any number may be used and having the sameconnections, and between which pair is placed the trip-dog E and lock c,connected and engaging with the pinwheel D. This construction enables meto place as many springs as I desire upon the shaft G, and the number ofrevolutions for winding any number of springs will be the same asrequired for winding one spring; and it will be readily seen that I havethe strain of only one spring upon the train of gear, thus enabling meto make the gears of lighter material and cheaper. The anti-frictionrollers or balls h6 b are placed in the hub of springwheel to relieve ortake away friction on shaft G of all spring-wheels at rest while theshaft G is revolving.

Vhen ready to operate the device, I wind up all the springs and operatethem and their wheels alternately. When one is running, the others areheld at rest by means of the dog E and lock c, and when one spring isrun down by means of the contact with the pinwheel D the other isreleased and it operates, `thereby continuin g the revolution of theshaft.

H is a revolving,r shaft, preferably outside of the standard A3, whichat the bottom is journaled in a suitable boxing provided withanti-friction rollers. This box or cup 7e has a circular groove d4 d4 atthe bottom, as shown in bottom plate A2 in Fig. l 0f the drawings, inwhich groove I place, preferably, one ball, upon which ball the standardH rests, and the ball travels around the circle with the rotation of thestandard. At a suitable distance from the bottom of this cup, and alsoon the plate F, I provide suitable anti-friction bearings c5 e5, asshown, to lessen the lateral friction of shaft H. On the bottom plateA2, and passing' through an auxiliary plate or bracket F, whichissecured to and projects from the top of the standard A3, (or it maybethe top plate F extended, the said plate F being provided with aboxingand suitable anti-friction rollers toward its lower end,) the shaft Hhas mounted thereon a cog-wheel h, which receives its powerfrom thegear-wheel C through one or more intermediate gears h', which arejournaled between the intermediate plates B and bottoni plate A2,through which the shaft H is revolved by the revolution of the shaft G.The shaft H extends above the top plate F', and is provided with a shelfor other suitable stand or connection F2, upon which goods may bedisplayed and revolved.

I do not wish to' confine myself to any specic number of springs orwheels, to any speciflc number of pin-wheels, or t-he specificarrangement and location of the various parts, as all of these may bearranged suited to the circumstances, as required. It is also evidentthat the pins on wheel D may be placed on the face or rim, as desired.

The manner of operation is as follows: All the parts being in properposition and the goods to be displayed having been placed on the shelf,and the springs having been wound up by turning the shaft G, and theshaft being held locked readyfor use by any suitable locking device,when ready for use the wound shaft is unlocked or loosened, when thelower spring-wheel B will, by force of the wound spring, commence torevolve, and, through pawl-an d-ratchet connection, carry around orrevolve the shaft G. This will revolve the and the Wheel 7L, revolve thestandard H, there- 4by revolving the goods on its shelf F2. While thespring-wheel B is revolving and expending its force, the pin CZ iscontacting at intervals with the pins d2 on the wheelD until the' wheelD is turned so that the pin d3 will strike the trip E at the time thespring B has been unwound, which trip E, by being struck, will releasethe dog or lock e, which has beenhold ing the spring-wheel A at rest orlocked,when its spring will begin to operate, turning its wheel, andthereby revolving the shaft G and keeping the device continuously inoperation.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a spring-motor, the combination of the shaft G, wheels A and B,mounted on said shaft and having springs A5, the springs being adaptedto be wound all at one time by t-he turning of the shaft G, the wheel D,having projections cl2 and cl3, the trip E, and lock e, whereby eachspring may be unwound alternately, substantially as shown and described,and for the purpose set forth.

2. In a spring-motor, the combination of a revoluble shaft havingmounted thereon a plurality of springs, and 'having the wheelsA and B,the pin-wheel D, having projections d2 and d3, the trip E and lock e,located between the springs, a gear-wheel on the shaft, and a revolvingshaft having a shelf for displaying goods and provided with a gearoperated through intermediate gears by the gear on the springshaft,substantially as shown and described.

3. In a spring-motor, the combination of the pin-wheel D, havingprojections d? and d3, the trip E and lock c, the wheels A and B, andspring I, substantially as shown and described.

4:. In a spring-motor, the combination, with the revoluble shaft G,journaled in the frame A of the springs A5, connected at one end to theframe, the wheels A and B, provided with the collar g, pawl g', and theratchet ce, and friction-bearings a2 a2, and the gear-wheel C,substantially as shown and described, and for the purpose set forth.

5. In a spring-motor, the combination of the gear-wheel C, having theratchetwheel C and IOO IIO
